The Yeelight Cube Smart Lamp - Light Gaming Cube Matrix - Expansion Pack is an extension to the base module. The base module is only available in a set with a Cube Spot, a Cube Panel, or a Cube Matrix. Create your own dynamic pixel art and transform it with just a touch into whatever you want - a digital clock, an emoji, or a billboard. Let your imagination run wild and create a unique artwork that reflects your individual style. This device requires the Yeelight Cube Base Station. This expansion does not include a base station; it is an extension for the Yeelight Matrix. To use this expansion, a Cube Base Station is required.
